A nine-tailed fox, a soaring phoenix and magical companions approach a glowing city. Two women ride mythical horses, with cats, two snails and a floating jellyfish amid violet light.

THE FIRST ULTRA WORLDS / COMING SOON

Worlds that live
on their own.

THE ARRIVAL / A FIRST GLIMPSEULTRA WORLDSMORE WORLDS

Ultrasim builds Ultra Worlds: places where artificial beings are born, learn, remember and build. Nothing is scripted.

01 / LIFE INSIDE

What happens inside.

They live.

Beings with their own needs, habits and memories, shaped by what happens to them.

They build.

Weather, seasons and scarce materials. Shelter, paths and villages emerge on their own.

They grow.

Bodies change, skills develop, and every world writes its own history.

02 / SAME RULES. DIFFERENT STORIES.

Ultra Worlds.

Every Ultra World is persistent and unique: same rules, different stories. Villages, valleys and wild places run around the clock, whether or not anyone is watching.

Glowing mushrooms, a winding creek and small woodland creatures in an enchanted blue forest.

A forest lit from within.

03 / WHY IT’S DIFFERENT

A world with
consequences.

Most AI worlds are chatbots in costumes. Ultra Worlds are physical: beings have bodies, the world has weather and consequences, and behaviour comes from experience, not from a script.
